If your current 16 GB memorycard is not good enough then Sandisk offers the solution in the form of a 32 GB MicroSDHC memorycard. Soon available in stores.
Sandisk pulled it off, creating so much memory on such a small card by using 32 nanometer and 3-bit-per-cell technology. The disadvantage is that the card gets a 2 classification, not the fastest memorycard, but enough for mobile devices.
The adviced price for this card is 200 dollars and is expected next month.
